Postscript: The South Pole and the Polar Plunge

After fourteen months on the Ice, I took three months off and then returned for the 2012 winter season. While most of the season was similar to the previous one, there were two significant new events. On February 1, I was selected to go on what is colloquially known as a Sleigh Ride. During the end of the summer season, a number of flights are sent from McMurdo to the South Pole Station to resupply it with fuel for the next year. Since these planes can hold about 30 passengers and would otherwise be empty, a handful of people are selected for a "field trip" to the South Pole. Once the plane lands, it takes about thirty minutes to transfer the fuel, allowing the passengers to visit the station and take pictures at the geographic and ceremonial poles. In a surprise move upon returning to McMurdo, the pilot did not immediately land but rather flew the plane over the disintegrating sea ice and McMurdo Station, banking sharply so that we could take aerial photos of the landscape. What fantastic views!

A few months later, in the deep darkness of the winter solstice, Scott Base hosted its annual Polar Plunge, in which people jump into the ocean through a hole in the ice, immersing themselves in 28-degree Fahrenheit (minus-2-degree Celsius) water. Having missed this event my first winter, I opted to take the plunge this year. A video of my jump is at the bottom of this post. Enjoy!

The station is built on stilts that are able to lift hydraulically; as the snow collects, the station avoids getting buried.

The geographic South Pole, elevation 9301 feet

I'm at the South Pole!!! After taking this picture, I did a big lap around the pole marker so that I could say I've run around the world. :)

Because the ice shifts about 33 feet per year, the location of the pole is recalibrated every New Years Day. Since I was there on February 1, the pole marker would have been within 3 feet of the actual pole. On one side of the marker is a tribute to Amundsen and his men who were the first humans to reach the South Pole on December 14, 1911,

Scott and his men arrived five weeks later on January 17, 1912, thereby losing the race to the Pole.

The ceremonial pole is a surrounded by the flags of the twelve original signatories of the Antarctic Treaty.

The Flight Back to McMurdo

This and the next several photos are some of the views I saw from the plane on the flight back to McMurdo Station. Unfortunately, I don't know the names of any of them.

Black Island's textured terrain

The peaks of Black Island

The dust trails on the north side of Black Island. Due to the wind patterns coming from the south, Black Island is generally snow-free, especially during the summer. This leaves a great deal of exposed rock and dust to be blown off the island onto the Ross Ice Shelf. Because this black debris heats up in the sun, it melts the snow underneath is much more quickly than would otherwise be the case, thereby creating pools, trenches, and other uneven texture in the ice.

This is the path created by the icebreaker ship in the sea ice so that the fuel and supply ships could make it safely to station.
